TEL ER ATTACHMENT FOR RADIATORS.

Application filed April 1%, 1923. Serial No. 632,812.

To all whom it may concern:

Be it known that I, CHARLES 'A. PIPEN- HAGEN, a citizen of the United States, and resident of Chicago, in the county of 'Cook and State .of Illinois, have invented a certain new and useful Improvement in Shutter Attachments for Radiators, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

My invention relates to shutter attachments for the radiators of automotive vehicle engines. Generally stated, it is the object of my invention to provide a shutter attachment with a readily attachable finishing bead which cushions the attachment, improves its appearance, preserves and protects its margins and protects the front face of the radiator from injury.

Other objects and advantages of my present invention will hereinafter appear. In

the accompanying drawings illustrating a preferred embodiment of my invention:

Figure 1 is an elevational view illustrating a preferred type of shutter attachment having the finishin bead partially applied thereto, the dotte lines illustrating the outlines of the marginal flange ofthe attachment as such flange appears before it is trimmed to fit any particular radiator;

Figure 2'is a view partly in section and partly in elevation illustrating such attachment' properly applied to an automobile radiator;

Figure 3 is a transverse sectional view of the finishing bead as it appears prior to its application to the flange of the attachment shell; and

Figure at is a fragmentary sectional view illustratin the finishing bead applied to the marginal ange of the attachment shell.

Similar characters of reference refer to similar parts throughout the several views.

The specific radiator attachment shown in the drawings comprises a shell ormain frame consisting of a single piece of sheet metal conformed to rovide a marginal flange 10, a forwardly dished central portion 11, having a rectan lar fenestration 12, the upper part 13 of said forwardly dished central portion constituting a thermostat housing when the attachment is of the t wherein the shutters are thermostatical y operated or controlled to regulate the flow of air through adapted to be cut,

the radiator in accordance with the cooling requirements of the engine. Suitably supported within the forwardly dished central portion of the shell 11 is a frame 14 which supports a plurality of shutters 15-15, the shutters being preferably 0 erated and controlled by a thermostat not shown) lo-' cated within thepart 13 of the attachment shell. I shall not burden this specification with a description of the preferred structural details of the shell, shutter frame, shutters, shutter operating mechanism, thermostat, etc, of the specific type of radiator attachment with 'which I prefer to combine the improvements of my present invention. It will cut invention is particularly desirable and useful when embodied in a radiator shutter attachment of either the manually operrated or automatic type which comprises a shell. or frame adapted to be variably restricted by shutters, the said shell or frame having a marginal flange, (illustrated at 10 in the present drawings), which is cut, or to the proper size and shape to fit an automobile radiator, the said flange being adapted to lie substantially parallel with, inproximity to and within the margins of the front face of the radiator with which the attachment is associated.

Radiator attachments of the type with which m invention is concerned are preferabl hel in position by means of a pluralit of ong slender bolts which extend throug the marginal flange of the shell or frame of In the accompanying drawings the said bolts are indicated at 16-46, the radiator being indicated at 17.

In manufacturing radiator attachments of the type with which my invention is concerned, it is oftentimes desirable to construct the shell or main frame of the device substantially as illustrated in the accompanying drawings, to cover its surfaces with baked enamel or other suitable finish and to leave it with a relatively wide marginal flange 10, subsequently to be cut to fit any given radiator or type of radiator. The ori inal margins of the flange 10 of the attachment herein shown are indicated by dotted lines in Fig. 11. Ihave found that when the flange 10 is trimmed, as herein explained, the aked enamel or other finish becomes more or less mutilated, this mutilation frequently involving an exposure of metal. These mutilated portions of the enamel at the edges of the trimmed flange are very unsightly. Moreover-,unless the said edges of the flange are re-enameled, or unless means is provided to protect the mutilated portions of the enamel and the exposed metal from the elements, moisture will find its way between the metal and the enamel, the metal will rust and the enamel will quickly be destroyed over substantial areas.

Heretofore after trimming the mar inal flange of a radiator attachment, it has een customary to provide its edge portions with a new covering of baked enamel. lhis procedure is, of course, more or less expensive and consumes a great deal of time. My present invention contemplates providing the edges of the trimmed flange with a resilient bead which adequately conceals the mutilated edges of the trimmed flange and affords other important advantages hereinaiiter mentioned. This head is in the form of apiece of rubber tubing 18, the length of which is substantially equal to the enmeter of the trimmed ed e of the attac ment flange 10. The wall 0 the tube is preferably quite thick as compared with the diameter of its longitudinal passage 19, the diameter of the latter. preferably approximating the thickness of the material of which the flange 10 is formed. The said tube 18 is split from end to end, as indicated at 20. The tube 18 is applied to the trimmed edges of the flange 10 in the manner illustrated in Fig. 1.

Being of rubber or other resilient material, and being longitudinally split, the tube or bead 18 may readily be cut to proper length and be applied to the flange 10, as herein illustrated. It need not be cemented or be otherwise fastened'in place, as it adheres closely to the front and rear surfaces of the flange 10 by reason of its tendency to resume its original cross sectional shape.

macaw It materially improves the appearance of the radiator attachment by givin it a marginal finish and effectively sea s and protects the metal whiclrhas been exposed and the enamel which has been mutilated durin the operation of trimming the flange. It ad eres so tightly to the front and rear faces of the flange 10 that it revents the ingress of moisture to the muti ated enamel or exposed metal at the trimmed edges of the flange. or head 18 constitutes an effective cushion between the flange 10 and the front face of the radiator. When compressed between the flange 10 and the front face of the radiator, by tightening the bolts 16, it adequately protects the radiator, prevents rattling of the radiator attachment and seals the flange 10 to the front face of the radiator.

What I claim is new, and desire to secure by Letters Patent of the United States, is:

1. In combination with a shutter attachment for radiators comprising a marginal flange of metal provided with a rust-preventing coating and trimmed at its outer edge to fit the front face of the radiator, a longitudinally split strip of elastic material extended along the trimmed edge of said flange embracing and gripping its front and rear faces to exclude moisture from the exposed metal, and means for drawing said flange toward the front face of the radiator to clamp said flange to and in said split strip and the latter to the front face of the radiator.

2. The combination set forth in the foreoing claim in which the elastic material is in the form of a split tube, the normal bore of which has a diameter substantially equal to the thickness of said flange.

In witness whereof I hereunto subscribe my name this 16th da of April, 1923.
